Operator Responsibilities; Inspection; Maintenance - BWT AQA perla Bedienungsanleitung

9 Operator responsibilities

You have purchased a product that is durable and
easy to service. However, all technical equipment
requires regular servicing in order to guarantee
optimal functionality.
Keep yourself up to date with regard to the quality
and pressure ratio of the water which is to be treated.
If the water quality changes, the settings may need
to be changed. Consult a specialist in this case.
To ensure proper functioning and to meet
the warranty requirements, a regular inspec-
tion must be carried out by the operator (ev-
er y 2 months), and routine maintenance
(EN 806-5) must be performed by the BWT after-
sales service staff or an installer authorised by BWT
to carry out maintenance (every 6 months).
Wearing parts must also be replaced within the
prescribed maintenance intervals in order to ensure
functionality and fulfil the warranty conditions.

Inspection

The operator must regularly perform the following
inspections.
Regenerative
Check and refill
Test water hardness
The hardness of the local drinking water and the
set hardness of the outlet water must be checked
and corrected if necessary (see Start-up section).
Visual inspection
Check connection lines and connections for leaks.
Check for dirt in the regenerative container and
clean and flush with clear water if necessary.
Cleaning
Sanitize the regenerative container
Disinfection
In unfavourable conditions, e.g. if the unit is located
in a warm room and has not been used for a long
time, it may require disinfection by our after-sales
service staff in addition to regeneration.
Additional disinfection is not required if regenera-
tions are performed regularly (by the quantity con-
troller or time override controller).
according to use
Once a month
Every 2 months
at least once a year
The intervals between checks are recommended
minimums and must be reduced accordingly for
sensitive consumer systems.

Maintenance

The BWT after-sales service staff or an ins-taller
authorised by BWT must carry out the following
maintenance work regularly.
We recommend that you enter into a maintenance
agreement with your installer or the after-sales
service team.
